The present invention relates to chairs and has for its prime object toprovide means whereby a rocking chair may be easily and quicklytransformed into a rolling chair particularly adapted for patients,invalids and the like.

Another very important object of the invention resides in the provisionof a chair of this nature which is exceedingly simple in construction,inexpensive to manufacture, strong and durable, thoroughly efficient andreliable in use and otherwise well adapted to the purpose for which itis designed.

This invention accordingly consists in the features of construction,combination of parts, and in the unique relation of the members, and inthe relative proportioning and disposition thereof, or as morecompletely outlined herein.

To en able others skilled in the art to'fully comprehend the underlyingfeatures thereof that they may embody the same by the numerousmodifications in structure and relation contemplated by this invention,drawings depicting a preferred form have been annexed as a part of thisdisclosure, and in such drawings, like characters of ref erence denotecorresponding parts throughout all the views, of which:

Figure 1 is a side elevation of the chair adjusted for rocking purposes,

Figure 2 is a similar view adjusted for wheeling purposes,

Figure 3 is a horizontal section taken substantially on the line 33 ofFigure 1,

Figure 4 is a perspective View of a prop frame,

Figure 5 is adetail elevation of the forward end of one of the arms, and

Figure 6 is a detail elevation showing an intermediate portion of one ofthe arms with the wheel mounted thereon.

Referring to the drawings in detail it will be seen that any preferredtype of chair 5 may be used mounted on the front legs 6 and rear legs 7.A rung 8 is disposed between upper portions of the legs 6. Elongatedbars or arms 9 are rockably engaged by means of straps or other suitablemeans 10 with the rung 8 and are curved downwardly and ex- Serial No.392,928.

tend rearwardly as is clearly shown in Fig ures 1 and 2 to terminateadjacent the rear end of the rockers 11 on the lower ends of the legs 6and 7. Brackets 12 are engaged with intermediate portions of the bars 9support 0 an axle 14 having wheels 1% journaled on the ends thereof.

Casters 15 are swivelly engaged with the rear end of the bars 9.- A rung16 extends between intermediate portions of the legs 7 and is engageableby a frame F rockably engaged with the bars 9 so that the wheel chassisformed by these bars and the wheels 1 1 and casters 15 may be lowered toraise the chair that is to raise the rocker 11 off the floor as is shownin Figure 2.

This frame comprises prop members 20 connected together by tie rods 21.The lower ends of the prop members 20 are pivotally engaged with thebars 9 while seat extensions 22 are formed on their upper ends to engagewith the rung 16.

hen the frame F is in the position shown in Figure 1 this attachmentdoes not in any way interfere with the rocking of the shaft but byrocking the chair forwardly the frame F may be engaged in the positionshown in Figure 2 and then by rocking the chair rearwardly it will besupported on the wheeled attachment.

The method of use and operation of the device is thought to be clearfrom the above description, further detail discussion thereof is thoughtto be unnecessary.

It is, therefore believed that the present invention provides a simpleand practical device adapted to accomplish, among'others, all theadvantages and objects above set forth.

lVithout further analysis, the foregoing will so fully reveal the gistof the invention that others can by applying current knowledge readliyadapted for various applications without omitting certain features that,from the standpoint of the prior art, thoroughly constitutes essentialcharacteristics of the generic or specific aspects of this in vention,and therefore such adaptation should and are intended to be comprehendedas fall within the meaning and range of equivalency of the invention ashereinafter claimed.

Having thus described my invention, what I claim as new is:

1. A wheeled attachment for rocker chairs comprising a pair of barsadapted to be rockably engaged at one end with a rung of the chairconnecting the front legs of the chair, said bars respectively curvingdownwardly and extending rearwardly of the chair, a wheel journalled oneach of the bars intermediate the ends of the bars, casters swivellymounted on the free ends of said bars, prop members pivotally engagedWith the bars adjacent the free ends of the bars, said prop members attheir upper free ends provided with extensions capable of engaging arung connecting the rear legs of the chair when said wheels and castersare in ground engaging position whereby to support the rocker above theround on said wheeled attachments.

2. A wheeled attachment for chairs comprising in combination a pair ofapproximately identically shaped bars provided at one end with means forrockably engaging a rung of the chair, an axle supported transverselybetween the bars, wheels journalled on said axle casters mounted on thefree ends of the bars, a frame structure rockably engaged with the barsadjacnt said free ends and comprising a pair of prop membersrespectively provided at their upper ends with a rung engagingextension, and capable of engaging a. second rung of the chair wherebysaid chair may be wholly supported on said wheeled extension, and tierods connecting said prop members.

In testimony whereof: I aflix my signature.
